JACOB CARTUN, 0F PHILADELPHIA, PENNSYLVANIA.

INDICATOR.

, To all whom it may concern Be it known that I, J ACOB QAIRTUN, acitizen of the United States, reslding at Phlladelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Indicators, of which the following is aspecification.

My invention consists of an improved form of indicator, and isespecially serviceable for use on motor cars or other vehicles as asignaling device to inform oncoming vehicles of the intention of the.driver of the vehicle upon which the indicator is mounted to either turnto the right or left or to stop.

One of the objects of my invention is to provide an indicator of theabove described type which may be controlledby the pushing ofelectrically connected buttons which may be conveniently locatedadjacent the seat of the driver of the vehicle.

for ringing a bell so as to attract the attention of an oncoming vehicledriver to infornr him of the intention of the driver of the vehiclehaving the indicator thereon to display a signal or that a signal isbeing displayed. 7

Another object is to so construct my improved invention that thepressing of any one of the electrically connected buttons will operatemechanism to display a respective signal and will also operate to lighta lamp and ring the bell.

A still further object is to so design the elements of my invention thatthey will be simple in construction and easily operated.

These objects, and other advantageous ends which will be describedhereinafter, I attain in the following manner, reference being had tothe accompanying drawings in which Figure 1 is a rear elevation of theprincipal operating device of my invention shown incloscd in a casewiththe rear cover of said case removed.

Fig. 2 is a section on the line wa of Fig. 1.

Fig. 3 is a face view of a three button switch which I employ.

Figs-4 and 5 are face views of single point switches which are usedrespectively to cut out connection between the battery and the lamp andbell.

Fig. 6 is a rear view of the casing shown Specification of LettersPatent. Patented Feb. 25, 1919.

Application filed June 30. 1916. Serial No. 106.807.

- electrically connected elements of my invention.

Referring to the drawings, 1 is a casing made of wood or other materialand is so designed as to be readily secured to the rear end of anautomobile or other vehicle. This casing has an opening 2 provided withaglass or other transparent member to prevent dust from entering thecasing, this opening being of such shape and size as to permit view ofany of a number of signaling Words or marks, these words as illustratedbeing Left, Right, and Stop which are painted or otherwise inscribed ona transparent disk or plate 3.

I preferably make this disk by attaching to a small spider or cross arm4, a series of ribs 5 made of pressed sheet metal or the like, andinsert within these ribs 5, a series of transparent celluloid segments6, 7. 8, and 9.

The segment '6 is blank, while the segments 7, 8, and 9, respectivelycontain the words Left, Right, and Stop.

The cross arm 4 has secured to it a shaft 10 which is rotatable withinbearings 11 secured to the lower end of a vertically positionedsolenoid, the latter being secured by a bracket 13- to the upper andinner surface of the casing 1.

The solenoid 12 has an angular core 14 movable therein in a verticaldirection when its winding or coil 14* is electrically energized, andcarries a toothed rack 16 which meshes with a pinion 17 on the shaft 10.

The core.14 is provided with a pin 15 which extends transverselytherethrough and projects beyond opposite faces 18 and 19 respectively.This pin operates with certain elements as will hereinafter be specifically described to limit to different extents the rotary movement ofthe disk 3.

A standard 20 is mounted on a bracket 21 supported on the lower portionof the casing, and this standard 20 is directly below and in the planeof movement of the core 14.

Two levers 22 and 23 are pivoted between their ends to the standard 21,and have hooks 24 and 25 respectively at their upper ends,

the hooked end 25 being at a higher level than the hooked end 24. Theselevers 22 and 23 are normally held in a substantial vertical positionwith their hooked ends out of the path of movement of the pin 15, sinceit will be understood that said latter pin moves upwardly when thesolenoid 12 is energized, and also moves downwardly due to gravity andthe weight of the core 14 when the solenoid 12 is deenergized.

The means for holding the hooked ends 22 and 23 outv of the path of saidpin consists of a spring 26 which is secured to the standard 20 adjacentits lower end, and presses against the adjacent edges of said hookedlevers. I

It will be understood that these levers 22 and 23 are respectivelypositioned adjacent the surfaces 19 and 18 of the core 14, so that thehooked end of the lever 22 may, under certain conditions as shown inFig. 1, be moved into the path of one end of the pin 15, while thehooked end of the lever 23 may be moved into the path of the other endof the pin 15, so as to arrest or stop the upward movement of the core14.

The lever 22 below its pivot point is provided with a plate 27,preferably made of iron, and this plate is located adjacent the outerend of an electro-magnet 28 and forms an armature. 'In like manner, thelever 23 is provided with a plate 29 which is adjacent the outer end ofthe core of an electromagnet 30. j

The magnets 28 and 30 are secured to an insulating board31 which ismounted on an upwardly extending arm of the'bracket 21, this board 31also forming a support for a main or common binding post 32 as willhereinafter be more fully described in connection with the wiring.

. The upper portion of the casing 1 has an electric lamp 333 connectedthereto, the bulb of said lamp being in register with the opening in thefront face of the casing 1, but is positioned to the rear of the disk 3,so that when the lamp is lighted, its rays will penetrate the celluloiddisk and clearly illuminate the latter, so that th indicating signalsmay be readily seen through the opening 2.

An electric bell 34 is positioned within the casing 1 in a convenientplace and will ring when current is passed through the solenoid l2 andthe magnets 28 and 30.

I provide a selective switch having three push buttons 37, 38, and 39.This switch is connected by three wires 52, 53, and 54 to the lamp,solenoid, and bell respectively. The switch is also connected with awire said wire being continued to the battery 56 and to the main bindingpost 32. a

The lamp is connected by a wire 57 to the main binding post 82, and thesolenoid is connected by a wire 58 to said main binding post. In likemanner, the bell also has a connecting wire 59 which is in electriccontact with the main'binding post 32.

The switch 35 is also connected by a wire 60 to the magnet 30, saidmagnet also being connected with a wire 61 to the main binding post 32.The plate 47 is connected by a wire 62 to-the magnet 28, said lattermagnet being connected by a wire 63 to the main binding post 32.

By this construction, it will be understood that the battery 56 is incircuit with all of the electrically operated members, and that bypushing any one of the buttons, the lamp will be lighted and the bellwill be rung and the solenoid 12 will also be energized to lift itsmovable core14. If the button 37 is pushed, the magnet 28 will beenergized, and thereby attract the armature 27 to swing the lever 22 soas to bring its hooked end into the path of the pin 15. On the otherhand, if the button 39 is pushed, the magnet mature 29, and thereby movethe lever 23 to position its hooked end in the path of the pin 15.

On the other hand, if the central button most position.

The lamp 33 may be thrown out of circuit by the movement of the switch63 or the bell may be thrown out of circuit by the movement of theswitch 64, said switches 63- and 64 being shown open in'the diagrammaticview illustrated in Fig. 11. It will-be noted,

however, that the fact that either the lamp or bell is out of circuit,does not effect the Y 30 will be energized so as to attract thearoperation of either the solenoid 12 or the magnets 28 and 30.

The parts areso arranged and designed that when neither of the hooks arein the path of the pin 15, the complete upward movement of the core 14,will, through the action of the rack'16 and pinion 17, rotate the disk 3into such position as to bring the word Stop in register with theopening 2 in the casing. This movement is attained by the pressing ofthe central button 38, and since the solenoid 12 remains energized aslong as the button 38 is held in its inner-position, the signal willremain in that position, however, when the button 38 is released todeenergize the solenoid 12, the core 14 will fall by gravity and therebyreturn the disk 3 to its normal position with the segment 6 opposite theopening 2. p

The core 14 is limited in its downward movement by a pin 11 which issecured in the bearings 11 and against which one end of the pin 15strikes.

If the driver of the vehicle intends to turn to the left, he presses thebutton 37 which causes the magnet'28 to be energized and swing thehooked end of the lever 22 into the path of the pin 15. This movement ofthe lever is very small, and hence said hooked end moves into the pathof the pin before the pin has risen to the level of said hooked end.

When the pin reaches the level ofthe hooked end, it is stopped thereby,and the movement attained by the disk in such upward movement of'the pinis sufficient to bring the word Left into register with the opening 2,such position being shown in Figs. 1, 2, and 6 of the drawings. If thedriver .wishes to display the Right signal, he presses the button 39,and in so doing energizes the ma et 30 to attract its armature 29, andthereby move thehooked end of the lever-23 into the path of the pin 15to arrest the pin 15 when it reaches and engages said latter mentionedhooked end.

As previously stated, the hooked end of the lever 23 is at a higherlevel than the hooked end of the lever 22, and therefore a greatermovement is attained by the core 14: when the hooked end of the lever 23is in its path than when the hooked end of the lever 22 is in its path,this difference in movement being sufficient to allow the word Left topass by the opening 2,'but to stop the disk when the word Right appearsin line with the opening 2.

The arrangement of the solenoid 12 in a vertical position permits thefreesliding of the core 14 without jamming or producing undue friction,the weight of said core being sufiicient to fall by gravity and to turnthe disk into a common normal position after each or any of the buttonshave been pushed. It will thus be understood that considering that theswitches 63 and 64 are closed, if the button 37 is pushed, current willpass from the battery to light the lamp, ring the bell, operate themagnet 28 to move its respective hook to limit the upward movement ofthe core 14:, and the solenoid will be energized to move said core tobring the word Left opposite the opening 2.

'In a similar manner, if the button 38 is gushed, the magnets 28 and 30will remain eenergized Ibut-the solenoid will move its core to itsuppermost position, and the lamp will be lighted and the bell will berung. On the other hand, if the button 39 is pushed, the lamp will belighted, the bell rung, the magnet 30 energized to move its hookedlever, and the solenoid 12 will be energized to move the core totheposition permitted by said latter hooked lever.

While I have used the words Left, Right,

and 'Stop as the indicating signals, it will.

be understood that these may be changed to suit conditions, and while Ihave described my invention particularly for use on vehicles and thelike, it may be used advantageously any place where it is desired tosignal or impart a differential movement to an element such as the disk3 of my invention.

While I have described my invention. as takinga particular form, it willbe understood that the various parts of my invention may be changed-without departing from the spirit thereof, and hence I do not limitmyself to the precise construction set forth, 'but consider thatI am atliberty to make such changes and alterations as fairly come within thescope of the appended the signals has reached said position, sub-est-antially as described.
